This inventionrelates to machines foruse in the manufacture of shoes and particularly to improved mechanisms for` positioning shoes and soles relatively to each other,a`s, 5 for example, in the cement attaching ot soles to shoes.

In relatively locating ashoe and its sole with the aid of mechanismsuch asthat disclosed in the copending application for VLetters latent of the UnitedStates SeriallNo.V 414,516, filed December 16, 1929, in' the-name of Sidney J.' Finn, the edge faces .of the rear portion ofthe sole are engaged by one pair of eelers and the sides of the counterporftion of the shoe are engaged by another pair of ieelers, the pairs of feelers being so constructedand operated'that the pair o-shoeengaging eelers islocated symmetrically `rvith the pair fof sole-locating feelers. rThis mechanism-is satisfactory under conditions where the prefitting of the heel-seatportion fitting of the sole extends sojfarforvvard that theV -untrimmed edge portions of `the lsole 'which must be engaged by thel sole-locating `feelers lie` beneath arear portion of the. shoe the sides of .which `arecunsynumetrical,A`

that is, have rightY and left characteristics, the :shoe-engaging feelers AWhichV engage'these portions of the shoe Will noty locate the shoe properly vvith respect `to `thefsole. Objects of this invention are to provide, in

a mechanism` of the kindj disclosed in the j 4Q prior. application abovementioned, means by which theshoe-engaging 'feelers may be,`

so set that when they are in` shoe-locating position in vengagement with -unsyrnmetrical portions of the shoe they Will locate the shoe properly With respect tothesole. Y In the illustrated embodiment of the invention, the shoe-engaging feelers :gare each mounted on a lever which isfpivoted between its Vends to one of the levers which, inthe prior construction, carry the feelers. The

rear ends ofthevfeeler levers are connected` 4togetherand[means is providedfor moving their rear ends equally inv the same direction.

Preferably, and as illust`rated'means is also provided by .which thatl vmovement can befdeinitely predetermined' in accordancev With right or left characteristicsof the'parf ticular shoe at the'points'Where the eelers engage it; In other respects the feelers are operated as inthe prior construction, withv the result that, When conditions aresuch` that i the feelers engage'portions oi theshoe thatv are unsymmetrical With, respect to the longitudinalmedian plane .which 'is equally spaced gaging feelers can be set, theone toward that planeand theotheran equal distance:away-1v Y from the sole-engaging -eelersthe shoeenf.

from it sothatthe shoe as a Whole Will be properlylocated with respect tothesole.,

The shoe-engaging feelers,.as disclosed in i the applica-tion above referred to, are carried on levers similar to the levers 18, 20, superimposed p upon them, jand fulcruined Y upon the same pins 122,24. ln the present Y construction, the forward half of the front V1e arm ot'each .of these, levers is removed,leav ingk leverstO, 2pivoted at 22, 24 and having movable plate 48..l In the present construction, shoe feeler levers 50, 52 are pivoted Vbetweenftheir Yen ds at 54, 56 t0 the forward endsoffthe levers 210, 42, f The rearjarmsof the l'leve'rsz50, 52 a'reofset upwardly (Figs... 2 vand 4)y so as to overl'ie acovc'r plate 58 and! are connectedtogether by a link` 60 the pivots,I

cally'arranged with respect to thefsole-engaging eelers, and the machine embodying Ythe present invention, as described, will open ate exactly in the manner set lforth inthe Vapplica-tion'referred to above and will locate a shoe symmetricallywith respect toits sole.

If, however, conditions'are suchthat theporto kfthe-f shoe bottom,-the shoe will Vnot vbe properly locatedwith respect to` the sole. 'Asillustrated in Fig. 3, it willbe seen that the amountthatthe side of the shoe A over# hangs the sole B at the lower side of theigure is more Ythafnthe amount the shoe ioverhangs thesoleat the upper sideof the ligure.

He then re# leases atreadle .tor permit movement ofthek carriage-26 forwardly over the pad, .that is,

towardV the left, tothe positionshown in Fig. 3. .",Whenfthe end 'of an end feeleif 9.0g Y Vmeetsthe endllof'the sole B or Vthe operatorsY thumb heldjadjacentto the end of the/sole,

Y liminary pressure and,if conditions are such p the end feeler is held againstifurther movement to the left and accordingly rocks a lever92 in a clockwise dlrect'ion, releasing a lever 94 whlchis moved 1n a clockwise direction by a spring `96 causing a-tooth 98 carried( 'plate 38 is moved forwardly to cause the soleengaging eelers 10, 12 to find and hold the sole in the position in which it was placed by the operator. The operator then places a shoe A, the overlasted portion of the bottom of which has been scoured'and coated with suitable cement, on the sole B and depresses a hand lever 102,'thus releasing an angle lever 104 which is thenmoved in a clockwise direction by arspring 106, one arm of the lever being connected b a pin 108 to the slotted plate 48 so that the plate is moved to the left, causing the shoe-engaging feelers 14, 16 to close uponthe shoe and position the shoe with respect to the sole B. Simultaneously withthe release of the lever 104, a lever 110 is released and is moved in a counterclockwise direction by a spring 112 to engage-a pin 114 carried b-y the central feeler member 90 and causes the eeler member to be drawn away from the sole. i If the side portions of the shoe engaged by the feeler members 14, 16 are unsymmetrical with respect to the shoe bottom, the stud 72 will be released and turned in the proper direction to cause the shoe-engaging feelers 14, 16 to locate the shoe properlywith respect to the sole, the shoe-engaging feelersbeing located by engagement of the slide 7 6 with one of the notches 78 in a definite, pre-V determined position. n Y

The operator then starts to apply the preas to make it desirable, swings a hand lever 116 in a clockwise direction, the lever acting through a link 118 to `retract the sole-engaging feelers 10, 12 so that they will not be caught beneath the shoe when final pressure is applied. 'The operator then trips the machine to apply the final pressure, the carriage 26 being thereupon withdrawn to its inoperative position toward the right. At the beginning ofV this return movement, the eelers'lO, 12 and 14, 16 areseparated by movement of the levers which carry'them toward the right relatively to the slotted slidermembers 38, 40. At the conclusion of this movement of the carriage 26, the lever 104 is returned to itsy inoperative position by engagement of a roll 120 carried by a leverwith a relatively fixed cam surface 122, and the latch on the lever 102 becomes operative not only to hold the Vlever 104 in that position but also to'swing terclockwise direction, thus causing theoppo-IA site end of the lever to engage a notch' in the lever-.92, the lever 92 being urged -intoplatch-` ing position by the spring'96. `By this mover mentgo the lever 92y thel feeler memberj904 will be thrust towardl gthe "left into its nor-fs mal position.
